Explanation

Let's solve the expression step by step following BODMAS/BIDMAS (Brackets, Orders, Division/Multiplication, Addition/Subtraction) rules:

18 - 6 / 2 + 4 * 3

1. Division first:
   6 / 2 = 3
   Expression becomes: 18 - 3 + 4 * 3

2. Multiplication next:
   4 * 3 = 12
   Expression becomes: 18 - 3 + 12

3. Now, solve from left to right:
   18 - 3 = 15
   15 + 12 = 27

The pattern of the series is:

1³ = 1, 2² = 4, 2³ = 8, 3² = 9, 3³ = 27

Following this pattern:

4² = 16 (skipped), 4³ = 64

So, the next number in the series is 64.
